Furthermore, we seek to identify companies that embrace innovation and foster &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;disruption using technology to maximize efficiencies, gain pricing advantages, and take market share from &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;competitors. We believe innovation found in companies on the &#x201c;right side of change&#x201d; are benefiting from &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;technological, demographic, lifestyle and environmental trends, and are often mispriced in today&#x2019;s public equity &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;markets. This mispricing is a key inefficiency that the team seeks to exploit through intensive fundamental research. We &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;pay particular attention to how management teams allocate capital in order to drive future cash flow; this includes the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;allocation of human capital, financial capital, and social capital. We believe successful allocation of such resources has &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;a correlation with key indicators of future performance. Price objectives are determined based on industry-specific &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;valuation methodologies, including relative price-to-earnings multiples, price-to-book value, operating profit margin &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;trends, enterprise value to EBITDA (earnings before interest, taxes, depreciation and amortization) and free cash flow &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;yield. Portfolio holdings are continuously monitored for changes in fundamentals. The team seeks a favorable &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;risk/reward relationship to fair valuation, which we define as the value of the company (i.e., our price target for the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;stock) relative to where the stock is currently trading. We may invest in any sector, and at times the Fund may &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;emphasize one or more particular sectors. We may choose to sell a holding when it no longer offers favorable growth &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;prospects, reaches our target price, or to take advantage of a better investment opportunity.&lt;/span&gt;&lt;/div&gt;</oef:StrategyNarrativeTextBlock>

Our process begins with &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;fundamental analysis to determine a company&#x2019;s private market valuation which is the price an informed investor might &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;pay for the entire business. The analysis includes reviewing key financial metrics, competitive positioning, industry &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;dynamics, and management quality. We compare this valuation to the public market price and invest where we see a &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;significant gap. To complement our fundamental analysis, we incorporate systematic tools that provide additional &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;insight into portfolio risk characteristics and factor exposures. We believe these tools enhance our decision-making by &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;informing portfolio construction and supporting a balanced risk and return assessment over time.

The ESG factors utilized in &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;the Fund&#x2019;s investment process may change over time, some factors may not be relevant with respect to all stocks and &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;may or may not be determinative in the security selection process.&lt;/span&gt;&lt;br/&gt;&lt;br/&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;We may sell a holding when its price no longer offers an attractive risk/reward, fundamentals deteriorate, or to manage &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;risk and reallocate toward more attractive opportunities.&lt;/span&gt;&lt;/div&gt;</oef:StrategyNarrativeTextBlock>

Furthermore, we seek to identify companies that embrace innovation and foster &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;disruption using technology to maximize efficiencies, gain pricing advantages, and take market share from &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;competitors. We believe innovation found in companies on the &#x201c;right side of change&#x201d; are benefiting from &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;technological, demographic, lifestyle and environmental trends, and are often mispriced in today&#x2019;s public equity &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;markets. This mispricing is a key inefficiency that the team seeks to exploit through intensive fundamental research. We &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;pay particular attention to how management teams allocate capital in order to drive future cash flow; this includes the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;allocation of human capital, financial capital, and social capital. We believe successful allocation of such resources has &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;a correlation with key indicators of future performance. Price objectives are determined based on industry-specific &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;valuation methodologies, including relative price-to-earnings multiples, price-to-book value, operating profit margin &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;trends, enterprise value to EBITDA (earnings before interest, taxes, depreciation and amortization) and free cash flow &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;yield. Portfolio holdings are continuously monitored for changes in fundamentals. The team seeks a favorable &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;risk/reward relationship to fair valuation, which we define as the value of the company (i.e., our price target for the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;stock) relative to where the stock is currently trading.

Furthermore, we seek to identify companies that embrace innovation and foster &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;disruption using technology to maximize efficiencies, gain pricing advantages, and take market share from &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;competitors.

We believe successful allocation of such resources has &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;a correlation with key indicators of future performance. Price objectives are determined based on industry-specific &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;valuation methodologies, including relative price-to-earnings multiples, price-to-book value, operating profit margin &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;trends, enterprise value to EBITDA (earnings before interest, taxes, depreciation and amortization) and free cash flow &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;yield.

We define small- and medium capitalization companies as those with market capitalizations &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;at the time of purchase equal to or lower than the company with the largest market capitalization in the Russell &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;Midcap&#xae; Index, which was approximately $&lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;109.86 billion as of &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;March 31, 2026, and is expected to change frequently. &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;We may also invest in equity securities of foreign issuers through ADRs and similar investments.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;We seek to identify companies that have the prospect for robust sales and earnings growth rates, that enjoy a &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;competitive advantage and that we believe have effective management with a history of making investments that are &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;in the best interests of shareholders. Furthermore, we seek to identify companies that embrace innovation and foster &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;disruption using technology to maximize efficiencies, gain pricing advantages, and take market share from &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;competitors. We believe innovation found in companies on the &#x201c;right side of change&#x201d; are benefiting from &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;technological, demographic, lifestyle and environmental trends, and are often mispriced in today&#x2019;s public equity &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;markets. This mispricing is a key inefficiency that the team seeks to exploit through intensive fundamental research. We &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;pay particular attention to how management teams allocate capital in order to drive future cash flow; this includes the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;allocation of human capital, financial capital, and social capital. We believe successful allocation of such resources has &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;a correlation with key indicators of future performance. Price objectives are determined based on industry-specific &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;valuation methodologies, including relative price-to-earnings multiples, price-to-book value, operating profit margin &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;trends, enterprise value to EBITDA (earnings before interest, taxes, depreciation and amortization) and free cash flow &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;yield. Portfolio holdings are continuously monitored for changes in fundamentals. The team seeks a favorable &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;risk/reward relationship to fair valuation, which we define as the value of the company (i.e., our price target for the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;stock) relative to where the stock is currently trading. We may invest in any sector, and at times the Fund may &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;emphasize one or more particular sectors. We may choose to sell a holding when it no longer offers favorable growth &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;prospects, reaches our target price, or to take advantage of a better investment opportunity.&lt;/span&gt;&lt;/div&gt;</oef:StrategyNarrativeTextBlock>

Credit risk is the possibility that the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;issuer or guarantor of a debt security may be unable, or perceived to be unable or unwilling, to pay interest or repay &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;principal when they become due. In these instances, the value of an investment could decline and the Fund could lose &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;money. Credit risk increases as an issuer&#x2019;s credit quality or financial strength declines. Interest rate risk is the possibility &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;that interest rates will change over time. When interest rates rise, the value of debt securities tends to fall.

If interest rates decline, &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;interest that the Fund is able to earn on its investments in debt securities may also decline, which could cause the Fund &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;to reduce the dividends it pays to shareholders, but the value of those securities may increase. Very low or negative &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;interest rates may magnify interest rate risk.&lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

Our process begins with &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;fundamental analysis to determine a company&#x2019;s private market valuation which is the price an informed investor might &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;pay for the entire business. The analysis includes reviewing key financial metrics, competitive positioning, industry &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;dynamics, and management quality. We compare this valuation to the public market price and invest where we see a &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;significant gap. To complement our fundamental analysis, we incorporate systematic tools that provide additional &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;insight into portfolio risk characteristics and factor exposures. We believe these tools enhance our decision-making by &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;informing portfolio construction and supporting a balanced risk and return assessment over time.

The ESG factors utilized in &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;the Fund&#x2019;s investment process may change over time, some factors may not be relevant with respect to all stocks and &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;may or may not be determinative in the security selection process.&lt;/span&gt;&lt;br/&gt;&lt;br/&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;We may sell a holding when its price no longer offers an attractive risk/reward, fundamentals deteriorate, or to manage &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;risk and reallocate toward more attractive opportunities.&lt;/span&gt;&lt;/div&gt;</oef:StrategyNarrativeTextBlock>

Furthermore, we seek to identify companies that embrace innovation and foster &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;disruption using technology to maximize efficiencies, gain pricing advantages, and take market share from &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;competitors. We believe innovation found in companies on the &#x201c;right side of change&#x201d; are benefiting from &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;technological, demographic, lifestyle and environmental trends, and are often mispriced in today&#x2019;s public equity &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;markets. This mispricing is a key inefficiency that the team seeks to exploit through intensive fundamental research. We &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;pay particular attention to how management teams allocate capital in order to drive future cash flow; this includes the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;allocation of human capital, financial capital, and social capital. We believe successful allocation of such resources has &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;a correlation with key indicators of future performance. Price objectives are determined based on industry-specific &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;valuation methodologies, including relative price-to-earnings multiples, price-to-book value, operating profit margin &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;trends, enterprise value to EBITDA (earnings before interest, taxes, depreciation and amortization) and free cash flow &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;yield. Portfolio holdings are continuously monitored for changes in fundamentals. The team seeks a favorable &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;risk/reward relationship to fair valuation, which we define as the value of the company (i.e., our price target for the &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;stock) relative to where the stock is currently trading. We may invest in any sector, and at times the Fund may &lt;/span&gt;&lt;span style="clear:both;font-family:Arial, Helvetica, sans-serif;font-size:9.02pt;;"&gt;emphasize one or more particular sectors.
